Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI): Clinical Guide

Overview

Calculates the HCT-CI from pre-transplant comorbidities to support allogeneic transplant risk assessment.

Clinical Significance

Higher HCT-CI scores are associated with increasing non-relapse mortality; interpret with disease, age and transplant-specific factors.

When to Use

• Use as structured clinical decision support when the required data are available and reliable.

How It Is Calculated

• The displayed variables are combined using the published equation or weighted point system.

Interpretation

• Higher HCT-CI scores are associated with increasing non-relapse mortality; interpret with disease, age and transplant-specific factors.

Worked Example

Enter verified patient data in the displayed units; MedicalC applies the published equation or point system.

Limitations

• Classification and prognostic tools can be misapplied outside their validated population.
• Missing, estimated or non-contemporaneous data may materially change the result.

Clinical Pearls

• Document the input values, units, date and clinical setting with the result.
• Use serial scores only when the same instrument and measurement method are used consistently.

Common Mistakes

• Using the tool without confirming entry criteria.
• Selecting overlapping findings that should be represented by the highest-scoring item only.
• Treating a classification threshold as a standalone diagnosis.
